The present invention relates to alkoxysilane-substituted diene copolymers, organic and inorganic hybrid complex compositions comprising the same and a process for the preparation of the same. The alkoxysilane-substituted diene copolymers are prepared by reacting a diene copolymer substituted by epoxy or hydroxy groups with a silane compound. Thus prepared alkoxysilane-substituted diene copolymer is characterized by the facts that it is in organic solvents and it is capable of being cured at low temperatures. The present invention also relates to a composition prepared by mixing the said copolymer with inorganic fillers and/or coupling agents. The copolymer of the formula (1) has high reactivity with coupling agents since it possesses reactive silane groups and thus provides the diene polymer composition as having improved compatibility with inorganic fillers. In addition, when the copolymer of the formula (1) is added to a sol-gel reactant, a substitution reaction proceeds smoothly even under mild reaction conditions and thus it is possible to introduce the third functional group to copolymer blocks.
